Answer:

Product of 6 and a number would be 6 $x\\$ .

Nine more than a number? $x/2 +9$

Combine a number and 7? Either 7x or x + 7.

Step-by-step explanation:

Question 1 is relatively simple. 6 is a constant, so it can be inserted into any equation and maintain the same value. "A number" could represent anything, so we'll represent it with a variable. This gives you 6x (also 6*x)

Question 2 is the same as the first with 1 more step added to it. A number, as previously stated, is represented by the variable x. You divide this by the constant value of 2 to give you $\frac{x}{2}$ . Nine more would add +9 to the expression. Your final answer would be $\frac{x}{2} + 9$ .

Question 3. Combine is a bit vague, but it could be either addition or multiplication. This could give you either $7x$ or $7+x$ .

Hope it was helpful.

Any even number raised to any power will remain even. (e.g. 2² = 4, 2³ = 8, etc)

Any odd number raised to any power will remain odd. (e.g. 1² = 1³ = ... = 1, 3⁴ = 81, etc)

So $(n+1)^{2^k}-n^{2^k}$ will always be even, since both

[even] - [odd] = [odd]

and

[odd] - [even] = [odd]

F the value of x decreases by 6, how does the value of m(x + 9) change?

Yuki888 [10]

start with y= m(x+9)

Use the distributive property:

y= mx+9m

Now you want x to decrease by 6:

so y ' = m(x-6) + 9m

Use distributive property again:

y'= mx - 6m + 9m

y' = (mx+9m) - 6m

y' = y - 6m

So the value of y decreases by 6m.

Since each angle of the hexagon is a 30 degree rotation just count the letters as you move and multiply by 30.
1. 120 degrees
2. 30 degrees

3/4 pound of Colby cheese costs $1.69. Find the unit price per pound. (3/4 pound=12)

Liula [17]

Answer:

2.25

Step-by-step explanation:

We can write a ratio to solve

1.69 x

------ = ---------------

3/4 lb 1 lb

Using cross products

1.69 * 1 = 3/4 *x

1.69 = 3/4 x

Multiply by 4/3

1.69 * 4/3 = x

x=2.25333

The first time a census was taken in Esinville, the population was 12,621. Each year after that, the population was about 6% hig

Sedbober [7]

Step-by-step
Population was 12.621 when it was measured

Next year it rose by 6%, so add that 6% to 100% and multiply with population measured

12.621 × (100%+6%) = 12.621 × 106% = 13.379,24

Since a man cant be 0,24, we count that as +1

13.379,24 = 13.379 + 1 = 13.380

That was for a year after measurement, now let's calculate for another year
Now, add those 6% to a new population number

13.380 × (100%+6%) = 13.380 × 106% = 14.182,8

since 0,8 isn't a man, instead we add again +1

14.182,8 = 14.182 + 1 = 14.183

now let's do it for another year after last, by adding those 6% to a newest population number

14.183 × (100%+6%) = 14.183 × 106% = 15.033,98

round it again to +1, since 0.98 isn't a man

15.033,98 = 15.033 + 1 = 15.034

that is it, now graph is in the picture.
